There are three prices: early bird (until 1/19), regular (until 2/16) and late (after 2/16).

A limited number of registrations will be held for those making an additional $40 contribution to the Mini Mermaid Running Club, a running club where girls from every walk of life spend six weeks learning that they are capable of more than they every thought possible. Learn more about this club by watching their video here!

Bib Pick-Up

Bibs can be picked up at the race start on race day. We will also have pre-race bib pick-up at Sports Basement of Sunnyvale on February 27th (11-8) and 28th (11-5).

Race-Day Registration

If the race has not sold out before then, race day registration will be available. If the race has sold out, it will be announced on this page, the home page and our registration page. If you don't see "sold out" posted clearly in all these locations, you can safely assume you will not be turned away on race day. Be sure to hit F5 (refresh) to be sure you have the latest version of the website page you are looking at.

Note Regarding Entry Fees

Fees for this race (and all Santa Clara County Parks races) are little bit higher than at most other venues. This is because the Santa Clara County Parks Department requires not only the usual permit fees, reservation fees and staff overtime fees (which can total 10-20% of the gross receipts), but they also require us to reserve 100% of the park picnic areas (at a cost of thousands of dollars) since our runners use the parking for those in the morning, plus require an additional flat 10% of the gross receipts.

A very sizeeable portion of each runner's entry fee will go directly to the Santa Clara County Parks Department. We regret that this forces us to increase entry fees so that the race can still exist.
